Elimination Reaction
According to Modern Chemistry book of 2006 Elimination Reaction is reaction in which simple molecules are removed and an entirely new compound is formed. The different molecules are removed from an original compound and detached completely. The leaving group is separated making two completely different compounds, as portrayed in the picture below.1-2 Eliminations mean that there are actually molecules lost in the reaction, such as the dehydration of alcohols (losing of H2O) and also the dehydrohalogenation of alkyl halides (losing HX)
E2 Mechanism
This was originally proposed by Sir Christopher Ingold in the 1920s. E2 stands for Bi-molecular elimination. Generally the reaction is a one step transition. It is often the reaction of what happens after an original reaction, a reaction that has already reacted.
E1 Mechanism
Two steps:
Ionization: The breaking apart of Carbon and a Halogen.
Deprotonation: The remover of an H positive
Generally the second or third reacting of the molecule. Often lacking in a base, or having a very weak base.
